what does "->" mean in swift when declaring functions?
example function
func example(titles: [String]) `->` [UIButton] {
}
and where could i find more docs on this topic (docs relevant to functions declaring in swift)?
Answer
There is no > in swift function declarations - someone botched up the HTML rendering in the page you were reading. It was supposed to be -> (an arrow made up of a hypen and the greater than operator) that's used to denote the return type of the function.
The text was supposed to read
func example(titles: [String]) -> [UIButton] {
}
Which means the example function has one parameter called titles of type [String] (array of String) and it returns a [UIButton] (array of UIButton).
